There were Muslims in Australia centuries ago, well...a couple of centuries ago anyway...Afghan cameleers.
Afghan cameleers in Australia - Wikipedia
Small groups of cameleers were shipped in and out of Australia at three-year intervals, to service the Australian inland pastoral industry by carting goods and transporting wool bales by camel trains.
In 1838, Joseph Bruce and John Gleeson brought out 18 of the first "Afghans", who arrived in the colony of South Australia in 1838. The first camel, which became known as "Harry", arrived at Port Adelaide in 1840.
In 1866 Samuel Stuckey went to Karachi, and imported more than 100 camels as well as 31 men. In the 1860s, about 3,000 camel drivers came to Australia from Afghanistan and the Indian sub-continent, along with more camels.
In the 1890s, camels were used extensively in the Western Australian Goldfields to transport food, water, machinery and other supplies. In 1898 there were 300 Muslims in Coolgardie.
Many of the cameleers and their families later returned to their homelands, but many remained and turned to other trades and ways of making a living. Today, many people can trace their ancestry back to the early cameleers, many of whom intermarried with local Aboriginal women and European women in outback Australia.

Maybe that's what the "Muslim influencer" is talking about.
But that's not "before humanity".
'Before humanity' would be before 'Adam and Eve'?
Maybe she's gotten a bit 'takeover-excited' in her mind lately, having seen the "March for Humanity", 90,000 protesters marching across the Sydney Harbour Bridge, and large protest rallies in other cities.
The population of Australia is 27 million.
