Perth Business Pulse

Culture Professional but relaxed. Influenced by the mining and energy sectors.
Lunch Break 12:30 PM - 1:30 PM.
Pro Tip The ideal window is 9:30 AM to 11:30 AM. Perth shares a timezone with much of Asia (Singapore, Hong Kong), making it a major hub for regional trade. The culture is professional but has a relaxed "West Coast" vibe. Personal rapport and a "fair go" attitude are appreciated.

San Francisco Business Pulse

Culture Innovation-focused and casual. Values disruption, speed, and technical excellence.
Lunch Break 12:30 PM - 1:30 PM.
Pro Tip Best reached between 10:00 AM and 4:00 PM. Expect a casual, tech-first vibe—informal language and dress are the norm. However, technical competence and speed are non-negotiable. Many in the Bay Area work non-traditional hours, but standard business times remain the safest bet.
