Immigration Minister Scott Morrison says he has received "enormous support" from his Sutherland Shire constituents over the government's hardline policies aimed at stopping asylum-seekers coming to Australia by boat.

In an interview with the local Fairfax newspaper, The St George and Sutherland Shire Leader, the federal member for Cook said he gets much encouragement from locals in his travels around the electorate.

''I get so much encouragement when I walk through Cronulla mall, go down the beach, or up to Miranda Fair,'' Mr Morrison said.

''On Australia Day we were at the fireworks at Cronulla and I was walking through the crowd and people were coming up to me to say 'g'day' and encourage me and congratulate me on what we had done so far, and basically saying 'keep giving it to 'em and don't back down'.''
