Cirrus, to be honest I don't know. I do know pilots who went through in their early-mid thirties. All were civillian professional pilots before joining, except one, who was previously a Nav in the RAAF.
I know they do stay in quite late (hence the 63 y/o Navy Acmn) plus the Army and Navy seem to be perpetually short of pilots so who knows?
Is there anyone here who currently works at Tamworth?
