Alan Moran (‘It's not your father's Australia’, Quadrant Online Oct.31) simplifies the reason for the objections of a majority of Australians to mismanaged mass immigration - one of the top five election issues - with the no-nonsense, non-‘racist’ facts that it reduces the availability of housing and infrastructure, and brings the “incivility” of immigrants coming from countries “where conflict is endemic”.

As an economist, he spends time on the economic illiteracy of swamping the country with hordes of people and the effect they have on Australia's inadequate housing, health services, and infrastructure that was barely working for the current population, already twice the optimal figure of 13 million.

Then comes the “incivility” of newcomers who are well and truly doing their best to not fit in with the host culture, but impose their own culture on their hosts, with little or no reaction from most politicians - the ones that can, and should, have done so well before now. They have imported dangerous, uncivilised people they can't control: instead they are busy trying to control the free speech of locals (including good immigrants) who object to indiscriminate mass immigration of the wrong people.

Easygoing Australians, including immigrants who have settled in and absorbed Australian culture publicly and honestly, while not forgetting their origins, like everyone else who came here after 1788, are no longer so easygoing about the sort of immigration we have now.

Moran writes that apart from obvious economic and infrastructure pressures of mass immigration, there is widespread perception that many migrants now are “free-loaders” hostile to existing citizens’ political standards; and they are inclined to violence. Muslims are regarded in this way by many. The Bondi massacre amplified those feelings, as do now the “constant pro-Palestian demonstrations”. These concerns are “unlikely to decline”.
