The result proved a landmark in the competition and meant the latter have shipped 68 goals in their last two matches
Fiji broke the record for the biggest victory at the Pacific Games with a 38-0 win over the Federated States of Micronesia on Sunday, going 21-0 up by the break before adding another 17 later.
Atonio Tuivuna cashed in at the weekend with 10 goals at a tournament that provides the possibility of qualification for the Rio 2016 Olympics for his country, though Micronesia are ineligible as they are not affiliated to the International Olympic Committee.
The Oceania Football Confederation tournament has been a tough one for the latter, with their Group A hopes already over after going down 30-0 to Tahiti two days earlier.
The landslide result set a new highest score at the competition, but will not be officially recognised as a record by Fifa as Micronesia are not ranked by the governing body.
Australia therefore retain the honour for the biggest victory in a Fifa-recognised international football match, having beaten American Samoa 31-0 in a qualifier for the 2002 World Cup.
