TRIPLE premiership winner Steve Johnson insists anything's possible for Greater Western Sydney as the Giants embrace their newfound status as genuine premiership contenders.

Far from playing down the hype, Johnson is backing the Giants to rise to another level after surging to a club-record four-game winning streak.

"If you had have said that we'd be 5-2 after seven rounds, you'd certainly take that given we probably missed an opportunity in the first round of the season (against Melbourne)," Johnson said on Wednesday.

"But sometimes those things can be a blessing in disguise.

"So since then, we've played really consistent footy and I think our best is capable of beating anyone."

The Giants have already proven as much, hammering Hawthorn by 75 points in round six during their stirring run to fifth on the ladder.

"We've beaten Geelong, who look like they're going to be a quality side this year, and we've beaten the reigning premiers quite well out here a couple of weeks ago," said Johnson when asked what gave him the belief the Giants could go deep in September.

"That certainly gives young players the confidence that they can go out there and expect to actually get a result on the weekend.

"There's still a lot of work to do and there's still a lot of improvement to come from this group.

"If we keep doing that and not get complacent, anything's possible."

Johnson is one of only three players with flags on the Giants' 44-man list, along with defender Heath Shaw (Collingwood 2010) and ruckman Shane Mumford (Sydney 2012).
