Section 92 of the Constitution says that trade, commerce and intercourse among the States shall be absolutely free, Pauline proclaims.

Some might say that the section refers only to the customs duties which applied between the colonies before Federation.

After all, the section does begin with the words, "On the imposition of uniform duties of customs, .....". But of course there has never been any sort of limit to Pauline Hanson's indignation.

So on behalf of voters in country NSW, especially in the electorate of Eden-Monaro, I have to ask what the National Party will be doing about this.

Absolutely free trade means that NSW cannot impose any sort of controls on animals and plants from any other State.

Queensland cattle with ticks or tick fever must therefore be allowed into NSW without restriction, as must blighted potatoes from WA.

Right, Mr Barilaro?

Mr McCormack?

Barnaby Joyce?

The job-keeper scheme must use the same computer models as the climate emergency crowd and the Covid forecasters. All run hot. Maybe there is a computer virus spreading?

Please, we cannot afford the water to process more coal, it will inevitably damage the water table.

There's no way we're getting what it's worth and profits aren't staying here.

Please ban all political donations so this scam stops. Please encourage new industries like hemp, sustainable energy etc.

Rodney Yeo, Rivett

Is the world pumping too much iron?

June 1 marks the start of World Haemochromatosis Week.

Haemochromatosis is the most common genetic disorder in Australia and causes your body to absorb too much iron from food.

It is easy to test, simple to treat but tragic to ignore because the excess iron overloads body tissues, damages organs and can cause premature death.

Many people suffer the effects of haemochromatosis without being diagnosed because early symptoms are common with other conditions and include tiredness and aching joints.

When detected early haemochromatosis can be managed easily through blood donations and is no barrier to a normal life or life expectancy.

For those who have little knowledge of how politics works: When politicians want a certain result in their favour, they get a well-placed mate to suggest it first.

It could be called "Tag Politics".

And so we have the Minister for Energy, AngusTaylor, recommending that the controversial $3.6bn Santos CSG project should be approved "as soon as reasonably possible".

His reason? To suddenly drive down those energy prices he's been in charge of for yonks.

And this in spite of the strong opposition of both Narrabri (64 per cent) and general respondents (98 per cent) to the project on the grounds that it could endanger the water table of the nation's treasured Great Artesian Basin, among other critical concerns.

In their version of democracy it appears Mr Joyce and Mr Taylor have little appetite for seeking the public's views.

They can just declare an emergency.

And now the "tag" is being completed with Mr Joyce promoting coal, nuclear and, you guessed it, GAS, as his preferred options to "keep your blue-collar jobs" in Tamworth ("Gas, coal, nuclear on table", NDL, May 27).

Weatherboard and Iron?

Any port in a storm.

But which town would he suggest for that Nuclear Power Station? Tamworth? Armidale? Narrabri?

And it should be remembered that this is against the billions the NSW State government has been pouring into New England as a designated Renewable Energy Zone.

Barnaby didn't bother mentioning that when he chose to denigrate Nundle's wind farm project.

Then there was the suggestion of funding a new coal-fired power station.

Mr Joyce seems to have forgotten the rant he recently gave to the Tamworth Business Council about how government money was borrowed, followed by his suggestion they should pay back the government's loan if they wanted more assistance in keeping their doors open.

It's obvious money is only short when the priorities of others don't agree with his own.
