Mortality of indigenous Australians is regarded as unacceptably high compared to other Australians and compared to indigenous minorities in other similar countries. Indigenous mortality is based on data from WA, SA and NT, although some of the data are unreliable.

Indigenous mortality is based on data from WA, SA and NT, although some of the data are unreliable. There are few reliable data available in Qld, NSW, Vic or Tas because Indigenous status is significantly under-recorded on the death certificate. The objective of the research is to devise and validate indirect methods for estimating indigenous mortality in sub-populations where there are significant proportions of indigenous people, and where designation of indigenous status on death certificate is unreliable. This would permit assessment of mortality differentials and trends in a significant number of Aboriginal and Torres Strait Islander communities in Qld, NSW, Vic and possibly Tas and provide new perspectives in the study of determinants of mortality in indigenous populations through comparisons of communities with relatively high and relatively low mortality, and allow population-based evaluation of the effectiveness of services and programs through surveillence of mortality trends and differentials. The methods rely on the basic premise that the total mortality of a population is contributed to by the mortality of its components in relation to their proportion of the total population. The units of analyses will be mainly municipalities. Mortality and proportion indigenous will be used in the comparison of municipalities with similar socio-economic and geographic characteristics, and mortality by municipality will be statistically modelled using various characteristics of these populations, including proportion indigenous (using ABS data). Methods will be validated by employing them on selected WA, SA and NT mortality data where designation of indigenous staus is considered reliable. Mortality estimates will then be made for indigenous communities in NSW, Qld, and other states.Read moreRead less

Considering the prominence of the NSW prawn resources, it is important that managers be equipped with the information necessary to manage the school prawn resource in a sustainable way that provides equity for all stakeholders. Despite its prominence as one of the two most important contributors to the prawn production in NSW, little is known about the population dynamics of this species.

Despite its prominence as one of the two most important contributors to the prawn production in NSW, little is known about the population dynamics of this species.
There is evidence to suggest that the school prawn populations in NSW may be overfished. Available information shows that the size of spawning populations in ocean waters may be declining and that prawns are being caught at sizes far shorter than those that would optimise biological “yield per recruit” under an F0.1 fishing policy.
The data which was used in this population modeling of the species had relatively low levels of precision. Estimates of growth and mortality with acceptable levels of precision are needed so that population models can be used with confidence to predict the outcomes of scenarios aimed at optimising the use of the school prawn resource. Out of a list of ten topics needing research, attendees at the Juvenile Prawn Summit assigned the highest priority for research to the study of growth and mortality of school prawns. Objectives: 1. To estimate values for parameters describing growth of school prawns. 2. To estimate values for instantaneous fishing mortality for school prawns. Read moreRead less

Summary
Heart failure is the inability of the heart to provide adequate blood to meet the needs of the body, leading to lethargy, breathlessness and an early death. The problem is increasing as the population ages and in Aboriginal peoples with high risk factor rates such as diabetes and high blood pressure. Effective treatment is available if diagnosed early. This study aims to assess who is most at risk so that effective strategies aimed at diagnosis and treatment can be formulated.

Serosurveys of blood borne viruses such as hepatitis C and hepatitis B conducted in Australian and overseas prison settings have found that over one third of inmates have been exposed to these viruses with higher rates detected in injecting drug users and female inmates. Few attempts have been made to examine the causes of mortality among prisoners following release from detention. Most interest has focused on overdoses in the period immediately following release; the aim of this study will examine all causes of death among individuals exposed to the correctional environment and compare these to death rates for NSW. Correctional centres house a largely male (94% in NSW) population with backgrounds of disadvantage in all areas, including Indigenous Australians, people of lower socio-economic status, those with a mental illness, and the intellectually disabled. There are currently over 21,000 (June 2001) prisoners detained in Australian correctional centres with approximately 39% housed in NSW. Fifteen percent of the NSW prisoners are Indigenous but comprise only 2% of the general population. The aims of this project will be to: (1) Identify all causes of death among ex-prisoners in NSW for the period 1985 to 2001; (2). Compare death rates in the study group with those in the NSW community; (3) Correlate pre-release health information contained in medical records with specific causes of death; (4) Compare causes of mortality among various sub-groups eg. injecting drug users, the mentally ill, violent offenders, and the intellectually disabled; (5) Examine causes of mortality between Indigenous and non-Indigenous inmates; and (6) use this information to develop pre-release programmes aimed at reducing excess mortality among this group.Read moreRead less

In the vast number of these deaths, no cause can be found leaving no clues for parents and care providers struggling with decisions about future pregnancies and how the risk may be reduced for all women in pregnancy. Fetal death before the onset of labour without an apparent cause (Unexplained Antepartum Fetal Death (UAFD) constitutes the most common cause of fetal death. In Australia, the rate of UAFD is approximately 2 per 1 000 births, contributing 30% to all fetal deaths. The rate of UAFD is over three times the current rate of Sudden Infant Death Syndrome (SIDS) in Australia. Despite this, little research has been undertaken in this area. The research which has been undertaken suggests that factors which are present during pregnancy may identify women who are at risk. However, the results of these studies are not consistent, largely due to the problems with study design, and therefore the available information is not sufficiently reliable to assist in identification of women at risk. Well designed, large scale studies are urgently needed to determine, from the reported list of risk factors, those factors which truly identify a woman at increased risk in the antenatal period where appropriate care can be provided to decrease the likelihood of fetal death. Recently, a collaborative effort involving clinicians and consumers in Australia has commenced to support and undertake research and related activities and to collaborate with international groups in reducing the risk of UAFD (ANZ Fetal Death Collaborative Group). This study forms the basis for this work within Australia. This study is designed to identify women who are at risk of unexplained antepartum fetal death. The study involves a review of 800 unexplained antepartum fetal deaths in three States of Australia and an analysis of information on all births in Australia which is routinely collected by Health Departments.Read moreRead less

Summary
The predation of 'pot caught' rock lobsters by octopus is the major cause of direct loss to fishermen in South Australia. In the Southern Zone Fishery it is estimated that on average 10% of all pots are predated by octopus. Octopus kill between 200-250,000 legal sized lobsters each year which represents and annual loss to the industry of between $5-10 million.

In the Southern Zone Fishery it is estimated that on average 10% of all pots are predated by octopus. Octopus kill between 200-250,000 legal sized lobsters each year which represents and annual loss to the industry of between $5-10 million.
In the Northern Zone Fishery (input regulated) predation results in direct financial cost to fishermen associated with the loss of saleable lobsters. In the Southern Zone Fishery (output regulated) predation results in indirect costs associated with increased time and effort expended to catch quota.
Prevention of octopus predation would generate greater income to fishermen in the Northern Zone and reduce costs and number of days required to catch quota in the Southern Zone.
In addition to the economic costs, a significant consequence of octopus predation is its impact on rock lobster stocks and the sustainability of the fishery. The loss of lobsters to octopus results in increased fishing pressure on stocks. Fishermen catch more lobsters than required to compensate for those killed by octopus. A reduction in the number of lobsters killed by octopus would enable fishermen to catch less lobsters without affecting existing income levels resulting in reduced pressure on an already heavily exploited resource. Elimination of predation may provide an important buffer against the threat of overfishing and significantly enhance the sustainability of the industry by reducing harvest levels by 200,000+ lobsters each year. Objectives: 1. Describe the spatial and temporal changes that have occurred in octopus predation level over the last 15 years. 2. Determine how environmental factors influence octopus predation levels over a fishing season. 3. Identify pot modifications that have the potential to prevent/reduce octopus predation of pot caught Southern Rock Lobster. 4. Trial pot designs to prevent/reduce octopus predation under laboratory conditions. 5. Develop a pot that under commercial fishing conditions, prevents/reduces octopus predation, maintains lobster catch rates and is cost effective to implement. 6. Ensure industry participation and consultation at all stages of the project. 7. Ensure adoption of the modified pot(s) by industry where appropriate. Read moreRead less
