Is Australia the core of the last supercontinent?

I saw something yesterday talking about how Australia is geologically dead with the lowest tallest mountain range of any continent due to no landmass collisions. Does that make it the last visage of a supercontinent that everything else broke away from?

I wonder of Australia’s relevance to the mantle anomalies speculated to be part of the Theia collision.
