Estelle, the Enduring Power of Attorney document shows a different address. See the PDF
Redacted Affidavit of Jennifer Williamson (pdf, 32.5 MB), filed 26 November 2020 from the index at
ASIC v Melissa Caddick - Online File. For me the page is 15 of 42 in the PDF, or it's handwritten as "13" in the footer of the page.
According to
onthehouse.com.au, the address in the affidavit has been listed for rent three times since the EPOA was signed on 15 Sep 2016: 23 November 2017, 12 March 2020, and 07 May 2020, but maybe "listed for rent" means it was advertised but not rented?
