Look at the native Americans in new France, missionaries went in a converted a lot, fur trappers (in your case goldminers) will "intermarried" (basically had kids) with the locals. Also French colonial society didn't generally have the hatred for natives anglo colonies did (which may have been due to the fact the French settled in small number unlike your scenario).not being sure how Franco-Aborigine relations would be
True, Algeria is after all much closer to France (a quick hop across the Mediterranean) than Australia is to France (a long @$$ boat ride to the other side of the world), but the gold rush is coming up and Algeria has a massive, disease-immune native population, while Aboriginal Australians will have likely been crippled by conflict and disease with European (mainly French at this point) settlers. In addition, it's possible that the French Australian governments could pay for travel to Australia like the British did in OTL.From the 1830's, Algeria will be the main contender for french and european colonists if the otl conquest take place.
British colonists had many other destinations available and populated Australia solely through Prisoners, OTL France had a higher population and didn't have any other natural destination available for colonists so they went to the United States, Canada, Australia and Latin America and assimilated with them numbering around 300 Million by 2009. So the population is kinda low.Sceonn I don't think tons of Frenchmen would want to move down under, considering that Algeria and Quebec both had troubles attracting settlers, but maybe the gold will help. Beside, the Italians will be quite keen on moving to Terre Australe (spoiler alert).
Also, the gold rush is the next update![]()
