The ascension of Scott Morrison as Prime Minister may not have delivered a boost to the Liberal Party's electoral chances but it's been a blast for the computer supply and printing industries.

More than $300,000 has been spent on business cards, letterheads, phones and computers for new ministers, their senior staff and advisers since Mr Morrison took over as Liberal leader in late August.

The sackings and promotions between the last ministry of Malcolm Turnbull and the first of Mr Morrison resulted in more than a dozen moves of parliamentarians and a phalanx of staff into new positions.

In answer to a series of questions on notice to Senate estimates, the Prime Minister's Department revealed it had forked out $5520 for business cards and $56,061 on new iPhones, iPads and printers.
