Does not really make sense. The French lost 7 year war but without a French threat in North America there was no reason to kick out the Quebecois. People get the impression that due to the British attacks against the Acadians they do the same to the Quebecois. But that was not the case, all attacks and deportation against the Acadians ended with the British victory over the 7 years war. The reason being that the actions against the Acadians had been as result of fear they would side with France which was still present in New France during a future war. This threat disappeared due to loss of New France and the expulsion of the French from New France.
Now no transfer of people in any case till the war ends. The French navy was occupied fighting the British Navy to send any ships to move 60,000 people. Plus moving 60,000 would be a huge undertaking taking many years in not over a decade. If by some magical means they had been transported to France what makes people think they entertain a year long journey to Australia which at time of the 7 year war had not been properly mapped. So there would not of been an Australia to move to.
Also settlement would of been a gradual process with first settlers setting up base camp an growing food to feed themselves and new settlers. Take decades to move the people there (as I indicated need to discover and explore it first before settling it.
Lastly the way negotiations happened during that time period was a trade not a conquest. The British offered the French New France back but the French wanted the Caribbean islands due to sugar plantations which were a money making process while New France cost money to operate. Even access to the fishing Grand Banks was viewed by the French as more lucrative and of vital interest to France than New France.
Lastly the French were in no financial situation having lost grand banks, Caribbean and New France to undertake transport and re-settling tens of thousand of settlers halfway around the world. Which incidentally was completely cut off from France in case of war.
