Seattle follows Pacific Time (UTC−8) and observes daylight saving time as Pacific Daylight Time (UTC−7) from roughly March to early November. Cairns uses Australian Eastern Standard Time (UTC+10) year-round and does not change clocks. This means Cairns is typically 18 hours ahead of Seattle in winter and 17 hours ahead in summer.

Visa and entry requirements for Australia depend on your nationality and the purpose and length of your stay. We recommend that you check official government sources or consult your local Australian mission before you travel, and ensure any transit requirements for Singapore are also met.
