I'm retired, so I can usually make my day time free of commitments.
On any day M-F, between 5pm-6pm I have commitments -- that's 3-4 for QLD, VIC and NSW
not considering DST changes. Weekends are problematic for me.
I'm normally up to around midnight, so lateness isn't a problem for me. I reckon most of you easterners will be in bed by then.
I feel I can make comments like that because prior to being headhunted to come to WA, I'd lived in QLD, NSW, ACT and VIC.
I'm sure we can work something out.
