Dear JohnR:

First, some really nice images there, I esp like the church interior.

Bit opinionated aren't we?
And somewhere here on UHH and elsewhere there are people who believe just the opposite of you and just as firmly.
That is OK, as long as they express it as their "opinion" or have factual evidence to back it up.

I have several cameras, not even counting all the film stuff I still have but don't use.
A FF (24x35 suit you better?), two different APS-C cameras and each has a different "crop factor", a bridge camera with a small sensor, and a pocket zoom with an even smaller sensor.
I also have a pile of lenses from ultra wide 14 mm to 600 mm in two brand's mounts. I do birds, flowers, butterflies and macro. throw in some cars and trains (esp interiors of the cars and engines at the railway museum I belong to) re-enactment events etc.)

And of course a smart phone with a tiny sensor.
That one is to me a phone, though my wife and daughter insisted I learn to text and even use emojis. They also insisted I learn to send snapshots of things with it.
I would still have my old flip phone (Hey! It made phone calls!) but my wife gave me the smart phone.
It was her replacement for one that fell off the top of her car (long story - she was talking to someone when she got in the car...) in front of the fire station just before the sirens went off and two rather large fire trucks came roaring out - phone parts for 50 yards down the street.
She didn't like it, screen too small to play her games - Pokemon Go and Ingress (sort of an international "Capture the Flag" game with local and national teams) and it was one day past the just return it for another one date - so I took it, my flip phone's hinges were cracking, and she got one with a 5" screen.
Two years later it is still smarter than me. It has apps that came with it and cannot be gotten rid of that do things I need a dictionary to figure out. But I did figure out how to put them in folders so I don't have what seemed like 100 icons on 4 pages to scroll through to find any useful ones. The ones I use most often are "calculator" and "light meter".

And she still "borrows" my phone to use when she plays. So at times she is using 2 smart phones two 7" tablets and a 10" Tablet plus our daughter's 10" iPad (she is in medical school and doesn't have time to play-so Mom keeps her accounts active. I found out she enlisted me, got me accounts for both games and that my gamer's name on my phone is "Toad Chef". When I ask where that came from I just get a stare with a bit of a Mona Lisa smile.

The closest I have come to Australia is working with Australian and New Zealand troops in Vietnam in the 60's.
But my oldest son visited in 2017, sorta. His army reserve unit went to Alaska, joined with a bunch of Canadian troops, taught them to use US gear and then they all got in C17 transports and flew non-stop with mid-air refueling to Australia where they jumped over some large air base playing the part of the Aggressor Force Invaders in some training exercise called "Talisman Saber". He complained for 3 months about how hard it was to get the smell of kangaroo poop out of his gear. I reminded him he volunteered to become Airborne Special Forces. He could have stayed a combat engineer and happily built or blown up things until he hit retirement. Then he wouldn't have "Invaded Australia" in company with a bunch of Canadians. They had a rather cute female TV reporter who flew down with them and we have video that shows him twice - and a bunch of Canadians with all ID and insignia striped off their uniforms popping up behind whoever was being interviewed and making faces, waving to the folks back home etc - they had been told they did not have clearance to appear on US TV or be interviewed so they figured out a way to get on TV anyway. Boys will be boys, especially around a cute girl with a microphone and TV camera.
