Siltation in the Tamar estuary was a problem long before the Trevallyn Power Station was proposed. Trevallyn Power Station is not small. It is rated at 102.8 megawatts. 

Twenty-four-hour hydro-power stations connected to the state grid are rated smaller than Trevallyn. Do you propose that Hydro closes them all?

The construction of an aluminium smelter in the Tamar Valley was contingent on the state government building a new power station. A power station in the Tamar Valley was the perfect solution. 

Would you rather have foregone the economic benefit of the smelter to Tasmania?

Trevallyn Dam spillway is 26.8 metres above lake bed level. Trevallyn Power Station hydraulic head is 130 metres. Bolting a power station to the dam is not feasible and would certainly not be as efficient as the present scheme. 

Duck Reach Power Station was rated at 300 kW, minute in comparison to Trevallyn. With modern technology that output would no doubt be increased. I would love to see Duck Reach re-built and operating and discharging water into Cataract Gorge. Let's get that done.

Trevallyn Pond is relatively small storage and therefore Trevallyn Power Station is a run-of-river station. It operates when there is water flowing in the South Esk River. 

If Trevallyn Dam was removed the South Esk would still only flow periodically. It would not be the panacea which the Tamar estuary requires.

It does not pay to be older these days as everything is a chore. 

We ring Centrelink and wait an hour to be connected only to be told to do it online. 

When you try to create an account it will not accept a home phone number, so if you don't have a mobile then you cannot have an account.

So it's back to ringing again to be told to go online, all this just for a new healthcare card, even when you go onto Centrelink itself they try to steer you to a computer to register.

When are they going to realise not everyone can afford to have all the mod cons, computers, mobile phones and so on?

Banking that is another thing, I deposit rent, at first, it was easy, then it changed to including a mobile number, now it is you have to have your mobile with you.

How about leaving things alone?

Things worked the old way before and there was no need to change to make things difficult.

He was only trying to make a horse do its best. The jigger makers welcomed the free exposure, they are now working 24/7 to fill orders before the start of the AFL season.

Fifty dollars would buy a jigger six months ago, today it will cost you $500 online.

Reliable pub talk warns the public that if they use a jigger on their body nasty sores can leave a permanent scar in the shape of a horseshoe. Drug users are switching from speed to the jigger.

When I first heard Darren Weir was using something illegal I thought a roll of sandpaper, ouch.

I for one am sick and tired of hearing about asylum seekers, let the government get on with what they are elected for - looking after all the people who already live here.

Whatever the pros and cons of the so-called Medevac Bill passed this week in Federal Parliament and whatever any of us may think about, on the humanitarian aspect, or on the other the message it might send to people smugglers in South-East Asia, I find the Prime Minister's response very intemperate. 

I would hope his advisers would caution him and encourage restraint. It's not just, to quote Rebekha Sharkie, the prospect of him peddling the politics of fear; but also this past week the indignity of having to watch a petulant national leader miffed at not getting his way. 

He needs to settle down and remember he represents all Australians including those who disagree with his well-known position on immigration. 

Some of us do not want a return of the Tampa 2001 election, nor the turn back the boats in 2013 either, thank you very much.

Congratulations to all the politicians who voted to take a compassionate and just stance towards asylum seekers on Nauru and Manus Island by supporting the medevac bill. The treatment of refugees in the euphemistically named offshore processing centres has been a blot on Australia’s moral and ethical landscape for nearly six years. 

It is wrong to incarcerate a group of people for an indefinite period for the sake of “stopping the boats”. Expecting them to come through this ordeal without psychological, mental and physical illnesses is beyond the pale. Savagely targeting this small cohort of boat-arrivals when there are thousands of “illegal” asylum seekers who have arrived in Australia by plane does not pass any fairness and justice test.

Clearly, border force should be directed to tow back the planes as well as the boats to ensure that this country remains asylum-seeker free.
