Here's one result I unexpectedly found. I had no idea my great-grandfather, Robert Wyllie, was a cemetery trustee. And ironically he is now buried in the same cemetery.
Gazette 156: Wednesday, August 27th 1924
It's certainly worth searching by key words such as place names, ship names, company names, and surnames. Here's a quote from the 'About the Gazettes' tab on the website:
They contain information on everything from land transactions, bankruptcies, reward notices and new acts of parliament, to tenders, patent applications, unclaimed letters and monies, shipping and emigration notices, and more.*Robert WYLLIE, son of William WYLLIE and Ann Megget CRANSTON was born on 19 Mar 1855 in McLaren Vale, South Australia, Australia.
