A Labor frontbencher has joked about Prime Minister Julia Gillard's visit to western Sydney next week, comparing it to a ribald British comedy series.

Ms Gillard will be staying at Rooty Hill for a week as she and her cabinet team make a pitch for votes in some of Australia's most marginal seats.

"There are so many different sort of double entendres you can do with this place," Mark Butler told ABC radio on Wednesday.

"I stay at the Penrith Panthers when I'm in western Sydney because I'm not sure I could check into the Rooty Hill RSL with a straight face.

"It just conjures up all these sort of Carry On films and Benny Hill episodes and Carry On Governing filmed at the Rooty Hill RSL."
