Bollywood actress Bipasha Basu has been having a fun time shooting for her first foreign film "Singularity" in Australia, but says it is draining her out physically.

"Whoa! It's been physically tiring...the shoot! Lots of camel riding, compensated by the awesome locations, " Bipasha posted on microblogging site Twitter.

She plays a Maratha warrior in the film, being directed by English-French director Roland Joffe.
