Some businesses believe wages might go up by as much as 6 per cent under the policies of the opposition, while others have predicted 12 or 15 per cent, he said.
This week has seen the wages issue ramp up on the campaign trail, with Opposition Leader Bill Shorten pledging to make an increase to the minimum wage a top priority if Labor wins office on Saturday.
On Wednesday, the opposition pledged a small claims tribunal for workers for those not paid their entitlements.
The policies come as the quarterly wage price index rose 0.5 per cent, or 2.3 per cent seasonally adjusted.
“At 2.4 per cent, private sector wages are growing at the fastest pace for over four years. And in just under two years, wage growth has lifted from 1.8 per cent,” CommSec chief executive Craig James wrote in a note on Wednesday.
In a press conference in Perth, shadow treasurer Chris Bowen said these were”very disappointing figures yet again”.
In a policy explainer video released this week, Council of Small Business Australia chair Mark McKenzie told small business ombudsman Kate Carnell that wages increases would “cripple” smaller operators.
“In terms of wages policy, we’ve rated the ALP as a fail.”
While the small business sector has “a lot of respect” for Mr Bowen, the sector would be looking to work with a possible Labor government on future wage increases, he said.
On Wednesday Mr Shorten told reporters it was clear the wages system wasn’t working for everyday Australians.
He committed to consultation between businesses and unions around industrial relations policy should he win on Saturday.
“I will bring businesses into the same room as unions. I’ll bring the small businesses too, because not all small businesses love big businesses,” he said.
