The first half of 2013 saw 2.3 million media tablets sold in Australia, almost equalling last year's total sales, and taking the number of users in the country to seven million, according to analyst firm, Telsyte.
Annual device sales revenue is estimated to exceed $2 billion in 2013.
"The market has become increasingly competitive, however, the iPad mini helped Apple retain market leadership in the first half of 2013," Telsyte managing director, Foad Fadaghi, said.
Based on current trends, Telsyte predicts Android-based media tablets will achieve greater unit sales annually than Apple's iPads by 2015 in Australia.
Samsung leads the market with almost 40 per cent of all Android-based tablets sold in Australia made by the Korean vendor.
Despite a slow start, Telsyte estimates Windows-based tablet sales to account for 20 per cent of the market by 2017, driven by business users and increase original equipment manufacturer (OEM) support.
Of the media tablets subscribed to Australian mobile networks in the first half of 2013, about 20 per cent were connected via LTE/4G.
