Canberrans are the nation's biggest online shoppers with nearly 80 per cent buying goods online, according to a new survey.

The 2015 Sensis e-Business Report found nearly 79 per cent of Canberrans bought goods online, compared with the national average of 61 per cent.

ACT residents led the nation on buying clothing, airline tickets, hotel reservations, books, music, and DVDs or games.

Canberrans also led the nation in ownership of digital devices including tablets, smartphones and televisions.

"The ACT is Australia's tech capital. Residents really love their gadgets such as tablets, smartphones and digital TVs," Sensis commercial director Rob Tolliday said.

Nationally, the report found men were more likely to purchase electronic equipment (39 per cent versus 21 per cent), videos, DVDs or games (28 per cent versus 21 per cent) and computer hardware (23 per cent versus 11 per cent).

Women were more likely to purchase cosmetics (21 per cent versus 6 per cent), groceries (22 per cent versus 13 per cent), books (46 per cent versus 32 per cent) and clothing, accessories or shoes (54 per cent versus 47 per cent).

"Surprisingly, on the consumer side men dominated online, spending $6,500. This was more than twice as much as women who spent $2,400 for the year," Mr Tolliday said.

"Men bought more video games and take-away food, whereas women purchased more groceries and cosmetics."

The report found 61 per cent of ACT businesses were focused on interstate sales, compared to 46 per cent nationally, and were equally most likely to sell to overseas customers.

"ACT businesses are five times more likely to specifically target overseas customers, sharing number one spot with Victoria," Mr Tolliday said.
