I agree with Christine . Although it’s distribution is tropical also on Christmas Island just of Sumatra.
I have images of nymphs and they look almost identical to yours .
I am aware how little info there is .The images I looked at and compared the leg colouring pattern and found them to be very close to your entry are from Storena Formosa and Storena maculata.
You might have the info I am attaching but if not there are 4 images of spiders in genus Storena http://ednieuw.home.xs4all.nl/australian/Spidaus.html
