On other matters

Mal (CP, 21/3). The casualisation of the workforce has been the direct result of excessive union demands. Too much militant unionism kills business. See the SA industry for a case in point. Mic, Cairns

Nick Dalton (editorial, 21/3). Universities might be “big business”, but they’ve become group-think factories where free speech is suppressed. They don’t deserve taxpayer support for that reason. Don’t believe it? Ask JCU’s Prof Peter Ridd. He has taken JCU to court over suppressing his free speech. Miss T, Tolga

Hard not to notice Warren Entsch is very active lately. There must be an election looming. Apparently he is now very concerned about Daintree residents. Could he get funding for a second ferry and green power? Local, Cairns

Re: cat regulations (texts, 21/3). I used to have a garden full of frogs, now my garden is full of fighting cats. The council urgently needs to act on this serious issue. Sandy, Cairns

On highway clean-up. Well done, Bob. Now, how about a free kerbside collection of vegetation to tidy up the suburbs. Ah See, Manoora

Re: bike riding. Is it an option to wear a helmet in Cairns? I see so many tourists and locals without one. Craig, Manunda

The new Liberal SA Premier (CP, 20/3) must drop the “40,000 household batteries” plan and get real about electricity generation for there to be any hope for SA’s defence industry. And no, a new extension cord to NSW won’t cut it. Woz, Parramatta Park
