Hamish & Andy's Gap Year held strong for Nine, winning 967,000 viewers across Australia's five metro areas, putting it in sixth spot, and helping Nine to take the biggest audience share, at 30.6%.
Seven took the second largest audience share, with 27.4%, followed by Ten with 20.1%.
Seven's Winners & Losers also made the top 10, with an audience of 867,000 – down on last week's 941,000, according to preliminary overnight ratings figures from OzTam.
