Australian death certificates contain much useful information - parents, children, marriage detail and burial detail, length of time in each Australian state (NB Depends how much information the informant knew, of course) The victorian ones are available online
http://online.justice.vic.gov.au/bdm/home (although not this weekend as the site is being updated! - as per the notice given). Certificate images cost $17.50 to download (6-7 pounds)
To download without paying an extra $1 for index lookup you need the registration number. The records given by Raylen have the following reg numbers
Rose Collins year 1968 ref 2361
Jesse Collins year 1933 ref 9370
Walsh Thelma Year 1982 ref 17897
