Last Post: Opposition must wake up if it wants to win back voters

So the ACTU is calling for more holidays and a shorter working week – that’s sure to fix our falling productivity.

The first week of the new parliament has confirmed that the Liberal Party is destined for a long period in opposition. Sussan Ley offers nothing new to the voters whom the party must win back.

OK, let’s say that against all probability we get to net zero by 2050. What then? Climate change is conquered? Power prices plummet? Industries revive? More likely the survivors cower in their darkened caves with the laughter of the rest of the world ringing in their ears.

The government wants its hydrogen funding back from Twiggy, we want our renewables funding back from the government (“ ‘We want our hydrogen funding back, Twiggy’ ”, 25/7).

Net zero qualifies as a “luxury belief” (a term coined by Rob Henderson for an idea or opinion that confers status on the believer and inflicts costs on the less well-off). A key feature is that it will dissipate once the believer is no longer insulated from the consequences.

The PM owes us a detailed explanation as to why his government is persisting with renewable energy given all the problems that are now emerging, not the least the ever growing and unknown final cost. Carbon emissions reduction in Australia is making no improvement to the world environment, given the lack of action by other nations.

The government insists its decision on beef imports from the US was “based on science”. We all know of another disastrous decision that was “based on science”.

The Chinese navy must really look forward to its next sunny cruise down here to check out Talisman Sabre, but what it doesn’t realise is that we have spent billions of dollars on new submarines that are so stealthy that they give the impression of not actually being there at all.

Michael Houldsworth, Townsville, Qld

Those who understand how China operates aggressively within its own boundaries and globally will not be comforted by the bizarre utterances of Andrew Forrest (“Suspicion of Xi now in past: Twiggy”, 24/7).
