Moves are underway within the Federal Coalition to find a compromise for the controversial 32.5 per cent backpacker tax, slated to take effect in July.
The agriculture industry is worried the tax will cause a labour shortfall and stifle the growth of the nation's $10 billion horticulture sector.
Some rural MPs are questioning whether the proposed tax will generate the full $540 million forecast by Treasury over the next three years.
The change will see foreigners on working holiday visas taxed 32.5 cents from the first dollar they earn, and a scrapping of the $18,200 tax-free threshold.
