Alexander Corsair, born in St Petersburg, came to Newcastle in Australia in 1887, most likely as a seaman. He moved to Western Australia, where he worked as a miner and mining carpenter. He became part of the tough world of outback mining communities, living in the mining camps and fighting for the rights of his mates.
Although he was over fifty, he enlisted in the AIF and was allocated to the tunnelling companies as a sapper, but seven months later he was discharged as medically unfit.
After the war he continued working as a carpenter for the railway department.
