Does the gap change during the year?

Yes, because of daylight saving. Until 4 Apr 2027: GST is 6 h 30 min behind ACST. From 4 Apr 2027 to 3 Oct 2027: GST is 5 h 30 min behind ACST. From 3 Oct 2027 to 2 Apr 2028: GST is 6 h 30 min behind ACST.

ACST next changes its clocks on 4 Apr 2027 (back 1 h, to UTC+9:30), then on 3 Oct 2027 (forward 1 h, to UTC+10:30). GST does not change its clocks.
