By the way it's not the 1960s, maybe it is like that in the west, but families don't just revolve around the male, believe it or not
What does that have to do with anything? I think Treloar and his wife made a sensible and perfectly reasonable decision. He stays in Melbourne where they both want to live, while his wife go to Queesnland for 5 months and continue her dream of being a professional netballer, something that was only going to happen for 5 months, and something plenty of families go through if a family member is a member of the military or a miner.
That way Treloar's wife gets to pursue her dream, and then comes back 5 months later to her home and where she wants to live long term.
