Fulham are set to host QPR on Friday night, and Symons is wary of the threat that Chris Ramsey's men can pose.
The Cottagers boss says that Charlie Austin is a potent weapon, but has warned his side that solely concentrating on the 26-year-old could be damaging, as the R's have too many other players that could harm them if they are not at their best.
"They’ve got a good squad of players and a good manager in Chris who’s a fairly young manager like myself who’s still learning the ropes a little bit but is very bright and hungry," he said.
“They’ve got very talented footballers, so we’ll expect them to be a big test. I’ve seen quite a lot of them this season and they’ve got good individuals who can cause you problems on the day.
“Charlie Austin’s an excellent player, as is well documented. Everyone’s seen what he can do over the years – he’s an excellent player and a massive goal threat for them.
“But if you focus solely on stopping Charlie Austin, they’ve got other good players who can hurt you as well. So we need to be conscious of him and his strengths and what he can do and how he can hurt us, and we need to nullify that.
Austin was heavily linked with a move to Newcastle United, in the Daily Mail, over the summer, but he has stayed in what has been a major boost for the Loftus Road club.
Already the striker has proved his quality, and racked up six goals in his first eight appearances, showing his nerveless finishing ability once again.
Austin's goalscoring prowess has helped QPR to climb up to 9th in the Championship table, but they have failed to win any of their last three matches.
Fulham, meanwhile, have started the season slowly, and they currently sit in 16th position, having only been victorious twice over the course of the campaign to date.
