Help me find this Australian female jazz singer's name

More than 15 years a go, an Australian friend made me a mix CD of Australian jazz. One of the songs was a vocal rendition of "All the Things You Are." It was just a woman's voice accompanied only by a piano. Her voice reminded me a bit of Sarah Vaughan, but more restrained, less 'woozy'. I lost this CD ages a go, and have long forgotten the singer's name. I figure in this internet age, it'll be simple to track down her CDs, if only I could remember her name! (Been racking my brains for years, to no avail...) Hopefully someone out there in Jazz Reddit land can help :-)
