About the Perth-London gap
Perth sits in the Australia/Perth time zone (UTC+8), while London uses Europe/London (BST). That puts London 7 hours behind of Perth right now.
These two cities do not handle daylight saving the same way, one adjusts its clocks seasonally and the other does not. The difference between them therefore moves by an hour twice a year, which is a common cause of missed meetings. The clocks above always show the live position rather than an assumed offset.
For scheduling, the practical overlap runs from 16:00 to 17:00 in Perth. Booking inside that band means neither party is dialling in before breakfast or after dinner.
