I am looking to try to find the birth place of an aunt of mine her name Helen Yelland born 22/9/1933 as privacy laws prohibit access under 100 years it is hard to find maybe there are other sources to find the answer

You may be able to find a birth announcement by searching through newspapers of the time, which you can find online at Trove http://trove.nla.gov.au/newspaper?q=. I did a quick search in Trove for Helen Yelland with no luck, however, if you know an area where you think she may have been born, or where a number of her relatives lived at the time you may be able to find mention of her birth in the local paper in the days after 22 September 1933.
Sorry I wasn't of more help on this occasion, best of luck in your search.
