Alongside the catastrophic human toll from Israel’s war in Gaza, the United Nations estimates 83% of all structures in Gaza City have been damaged or destroyed.

So where should the rebuilding effort even begin? Construction expert John Tookey says food, medicine and bottled water will be immediate priorities. After that, attention will turn to restoring assets such as power, water and sewerage.

Realistically, it will take decades to design, finance and reconstruct infrastructure – and that’s only if peace holds.

Perhaps there are lessons from the past – 80 years ago, Nagasaki was razed by an atomic bomb. Gwyn McClelland explains how its residents managed the painful process of starting over with virtually nothing.

Indonesian accountability
"This article suggests holding Indonesia to account over the murder of Australian journalists in East Timor back in 1975. This is a worthy endeavour. Let us also not forget their appalling record in clear felling native forests for palm oil plantations, their illegal fishing in the Arafura sea, their ethnic dilution practices in West Papua and turning a blind eye to religious persecution of Christians and others in Aceh and elsewhere."
Ben Schutte

EV charging
"I feel you missed the elephant in the room: disability access. If you look at the picture in your article, it shows a common fault in installed EV chargers in Australia: the charging pedestal (ie the cabinet with cables etc) is installed on a concrete plinth which makes it extremely difficult for a person with a disability to reach the controls or cable dock. It is unnecessary: the hardware is designed to install at road level."
Doug Foskey, Lismore NSW

Malnutrition in aged care
"Over the past two years I have visited my father at his nursing home weekly and often at meal times. Six residents are wheeled to a communal dining table where their meals are delivered. I would say at least four with dementia sit and look at their meals but, without help, fail to eat anything. The meals are whisked away half an hour later by a staff member, often untouched. No wonder malnutrition ensues."
