The west London side were, at one stage, one of the best teams in the top flight based on home form, having endured most of their struggles on their travels.
QPR have since picked up their first away win - but results at home have dwindled.
And Austin knows the R's' best chance of staying up will come via turning Loftus Road into a 'fortress' once again.
"We need to get more points at home and turn it more into a fortress like we did earlier in the season," he said.
"We are a tight-knit group. No-one wants to get relegated, no-one in the club wants that to happen.
"There are lads here that were relegated before in 2013 and know that feeling - we don't want that feeling to happen again. We have come together and we know what we need to do."
As Opta stats show, QPR's home form was considerably better before the New Year than it has been since.
The R's have only played three games at Loftus Road this calendar year but have failed to win all three, only drawing once - against Swansea City. Compare that to their previous average of just under two points per game at home heading into 2015 and you can immediately see the problem facing Chris Ramsey.
QPR have faced tough tests in Manchester United and Southampton at home since the turn of the year - but that didn't seem to affect them when they took on the likes of Manchester City and Chelsea at Loftus Road before.
And the R's will need to start taking home points against top sides again soon - as Arsenal visit tonight and Tottenham on Saturday.
