Why people convert Jakarta to Perth time

Scheduling a call from Jakarta to Perth: a 10:00 AM start in Jakarta lands at 11:00 AM in Perth, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Jakarta and Perth are inside the 9-to-5 working day between 9:00 AM and 4:00 PM WIB time (10:00 AM–5:00 PM AWST). That is roughly 7 hours of usable overlap.
Watching a live event or market open: Jakarta viewers need 10:00 AM in Perth to catch a 9:00 AM start there, and 11:00 PM if the event is anchored to Jakarta.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM WIB as the recurring meeting window if you work primarily from Jakarta and need Perth colleagues present.

About WIB (Western Indonesia Time)

Western Indonesia Time (WIB, Waktu Indonesia Barat) is one of Indonesia's three time zones, fixed at UTC+07:00 all year. It covers Java, Sumatra, West Kalimantan and the provinces around them — home to Jakarta, the country's capital and largest city, plus Surabaya and Bandung. Indonesia does not observe daylight saving time, so WIB never shifts. WIB shares its UTC+07:00 offset with Indochina Time (ICT) and Christmas Island Time, but is a distinct zone covering the western half of the Indonesian archipelago. The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.

About AWST (Australian Western Standard Time)

Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.
