ANGRY WA farmers have dumped tonnes of grain on the front doorstep of the Premier's West Perth office saying the state government's financial relief package is meagre.

The Rural Action Movement poured the grain onto the driveway of the premier's new Hale House office in West Perth in the early hours of this morning.

Mr Barnett said later he was not stressed by a stunt by disgruntled farmers who dumped grain outside his office.

RAM President and Salmon Gums farmer Greg Kenney said the group would clean up the grain later - but not before the point had been made that the WA government was not doing enough to help struggling grain growers.

``This is serious,'' Mr Kenney told reporters.

The state government last month announced a $7.8 million emergency aid package for farmers on the brink of financial ruin after Mr Barnett rejected a call by the WA Farmers Federation for a $100 million low-interest loan scheme.

The package includes a one-off payment grant of up to $25,000 for up to 400 farmers who face losing their businesses.

Days later, the federal government announced $60 million in loans over two years to help farmers across the state restructure debts.

Mr Barnett said he didn't care who dumped the grain and labelled the Rural Action Movement a ``fringe group'' of the agriculture industry.

``It's a protest. I don't think, in any way, it reflects the view of the majority of West Australian farmers,'' the premier told reporters.

``It's a stunt, so be it. It doesn't cause me any great stress.

``It will get swept up and hopefully get fed to birds or other pets.''

Mr Barnett insisted his government was doing what was right for WA farmers.

Last year, low rainfall and some frost damage, particularly in the central and eastern Wheatbelt region, almost halved the state's wheat crop.

However wheatgrowers have been boosted this year by good early rains which have assisted the beginning of seeding operations.
