Time in Mackay, Australia

Mackay does not change its clocks
A fixed offset, all year round
Mackay stays on Australian Eastern Standard Time at UTC+10:00 every day of the year. There is no spring-forward or fall-back here, which puts it with the majority: most of the world's time zones do not observe daylight saving.
That sounds like it makes scheduling simpler, and locally it does — but it introduces a different trap for anyone working with Mackay from a country that does change clocks. The offset between you and Mackay is not constant: it changes when your clocks move, even though nothing changed here. A recurring call that has run at the same local time for months will shift by an hour, from your side, without anyone editing the invite.
When the gap to Mackay changes
Dates in the next year where the difference shifts, by counterpart city
The difference between two cities is not a constant. It changes whenever either side moves its clocks — and because regions switch on different dates, there are short windows each year when the usual gap is wrong. These are the dates that matter for Mackay:
Singapore (Singapore)
Neither Mackay nor Singapore changes its clocks in the next year, so the gap between them stays fixed. One less thing to track.
Tokyo (Japan)
Neither Mackay nor Tokyo changes its clocks in the next year, so the gap between them stays fixed. One less thing to track.
Los Angeles (United States)

How Mackay's clock got here

When the clocks change here
Clocks go forward on the last Sunday in October, a rule the tzdb has applied since 1991.
Before any of this, Mackay kept local mean time — solar noon by definition — at UTC+10:12, until 1895. Standard time zones were an attempt to replace that with something people could agree on, and the Mackay clock still carries the residue of that original figure.
Every date above is a record in the IANA Time Zone Database, not an estimate. The database is maintained by volunteers who track official announcements; if a government changes its rules, these figures change with it.

Same offset (UTC+10:00), different part of the world
These sit in other countries but keep the same standard offset as Mackay (Australian Eastern Standard Time). They will not necessarily change clocks on the same dates, so the match can be seasonal rather than permanent.
