Queensland has about 65 percent more sex shops now than it did two years ago, The Brisbane Sunday Mail reported. With 180 adult stores, Queensland has twice as many sex shops as Blockbuster video outlets.

EROS, the trade group, said capping the number of sex shops and regulating them more strictly would halt the proliferation of stores and allow the government to crack down on sales of illegal items. Queensland bans the sale of the most explicit DVDs and restricts the sale of some magazines.

Family First, an advocacy group, also wants to limit sex shops, saying too many are opening in suburban areas.

"I've had so many families say they don't want their children confronted with these sexual images and issues in suburban areas," Family First Chairman Peter Findlay said.
