The best and natural way is to mimic the local time as much as possible.
When it is 7 p.m. Eastern Time, it is 9 am in Brisbane. In early October, it will be 10 am. Daylight savings time ends 11/1 in the U.S.
In other words,
now: Eastern time 7 pm, Brisbane 9 am (Brisbane is almost like 10 hours earlier)
October: Eastern time 7 pm, Brisbane 10 am
November and later: Eastern Time 6 pm, Brisbane 10 am. (Brisbane is almost like 8 hours earlier)
Before the trip, try to get up as late as possible. If it is November and you can get up at 7:30 am that is like getting up at 11:30 pm in Brisbane.
When you are in Brisbane, sleep as early in the evening as possible. If you can swing a 6 p.m. bedtime and get up at 2 am, then the difference in jet lag is merely 2.5 hours.
More sleep is better than less. If you must nap in the middle of the day, try 30-45 minutes, no more. Then try to go to bed at normal local bedtime.
