The Diamonds are wary heading to their final pool game against world number four Jamaica as it decides who will finish on top.
It was a convincing win for the Diamonds as they cruised to a 118-23 victory over Fiji yesterday afternoon.
It was their third highest score in Commonwealth Games history.
Australia has only conceded 121 goals so far and scored 341 goals but after a successful Quad Series in January and Constellation Cup in October 2017, the team have put pressure on themselves to do well and defend their gold medal from Glasgow.
"We put a lot of pressure on ourselves to continue to better our best and although the matches haven't been that close in terms of scorelines, they definitely have been hard fought contests," defender April Brandley said.
"We've been fortunate we're capitalising on the turnovers that our defence end is working quite hard for," she added.
The Diamonds haven't played Jamaica since the Netball World Cup in 2015 where Australia came away with a 67-56 win to progress to final.
Australia went on to be crowned Champions.
Jamaica knew the pressure was on to defeat Barbados tonight if they wanted to have a chance to be top of Pool B and they never looked back as they led every quarter in their 76-32 win.
Diamonds coach Lisa Alexander said her side has to go out and do their job tomorrow night.
"We know when we come up against Jamaica on Wednesday it's like a final, it is the final game of our pool," she said.
"They've got some great Jamaican flare and athleticism so we are going to have to be on our best game to get a win."
