About UTC+10:30
UTC+10:30 is 10 hours 30 minutes ahead of Coordinated Universal Time: when it is noon UTC, it is 10:30 PM at UTC+10:30.
No zone keeps UTC+10:30 all year: it is only used as the winter time of some zones and the summer time of others.
1 zone uses it only in winter and moves to UTC+11 in summer, for example Lord Howe.
2 zones reach it only in summer, from standard time UTC+9:30, for example Adelaide and Broken Hill. So the set of places on UTC+10:30 changes twice a year.
Offsets with half hours are a minority: of the 39 offsets in use, 13 are not whole hours. Countries usually choose one to put a single clock between two whole-hour zones, close to the sun in the middle of their territory.
Abbreviations for UTC+10:30: ACDT (Australian Central Daylight Time), LHST (Lord Howe Standard Time).

UTC+10:30 converted to other offsets
Fixed offsets only, so the table holds on any date; a city that observes daylight saving time is an hour later than its standard column in summer.
