The men entered the last day of the qualifying draw needing just one more win over Samoa after they had dealt with Guam, Indonesia, Hong Kong and Iran over the previous two days.
They continued their solid form, reaching the 21-point mark while holding Samoa to 11 and with five wins from five games, Australia finished on top of the qualifying draw ladder to book a spot in the main draw.
There is no time for rest for the Aussies as they will be back on court against Kazakhstan (at 6.45pm AEST) and New Zealand (at 8.35pm AEST) tomorrow night in Pool D with just two games played in the pool stage.
Finishing in the top two of the pool will be enough for them to advance to the Quarter-Finals and every final will be played on Tuesday, culminating in the gold medal game at 11.15pm AEST.
The Aussie women also took on Samoa today and they flexed their muscle with another dominant performance, winning 22-8 after similar double-digit victories over Thailand and Sri Lanka yesterday.
That means they will take on Japan (at 6.05pm AEST) and Iran (at 7.35pm) in Pool D tomorrow and in the same fashion as the men, a top two spot will be enough to advance to the Quarter-Finals on Tuesday.
