Anybody know what citrus this is please ?

Do they have spinosad down there? Works well for leaf miner here, or you can just not feed after spring as an alternative.

Yeah...ive been going more for the concentrated form of feeding in spring to get as much growth as i can before the CLM turn up in the warm weather......i will have a look for spinosad here then....up to now...i use eco oil and neem oil with a little fish emulsion....but they just murder new growth...esp on lemons......its the urea they seek.

For a complete elimination of insects listed below, and for ultra safe personal protection, use a good horticultural oil.  It eliminates most all common insects that attack citrus. Can be sprayed between 32F to 90F.  Insects NEVER become immune, no matter how often or how long horticultural sprays are used.  Be sure to keep ingredients (water & oil) blended while spraying

Insects killed:
Rust mite, red spider mite, scales, white fly, thrips, mealy bug, aphids, Greasy spot, loosening of sooty mold.

my biggest problem in western australia is CLM.....they are a right pain....i dont even feed my citrus in autumn because clm will just decimate it...tried eco oil and neem oil and they just treat new growth like CLM candy........spring is where its at for me..before they turn up...they love the urea apparently.

Yep.....its the small young trees that can be severely effected by it......a big tree like that has so many leaves...it can easily spare a few to CLM.
I havent sprayed much this year in Perth and as yet...they dont seem to be around...which i find strange.....they usually appear with the spring flush.

as below.

Hi Millet.....No i have never heard of this trial..........relative to where i live in Perth...we dont need greenhouses at all.......in fact i use shadecloth on a regular basis...once it goes over 30C i have to shade cloth all my citrus and peach/nectarine/avocado/strawbs because they get cooked to death and we are not even in summer yet.......just before xmas we usually get a few 40 + C ...usually 42/43/44....so being a fat boy slim....i dont look forward to those times but Perth would be the perfect place to field test the technology.........most times of the 3 months of summer......we get no rain at all.

I have found feeding organically through the winter really helps because it breaks down slowly and is available for the spring burst when the trees need it....all my trees starting growing in the last month of winter ....my spring feed consisted of troforte....which is a cheiacl based feed with beneficial bacteria/fungi component and minerals......feeds for 6 months slow release......I am not seeing much CLM at all.... maybe because there is not much urea in the soil now and thats what the CLM are after.

LoL

Well i think i am fully qualified to comment on this subject because i have been tortured by citrus leaf miner here in Perth western Australia....I have done my research and have my 2 cents worth.......there is not much else that terrorizes  young citrus in perth ...except leaf miner.........But i can give you some tips.......they are very hard to pin down and you wont avoid them all together but you can try your best........Knowing your enemy helps....
Firstly.....what are leaf miner up too and what do they seek ?........they tend to come out to coincide with new growth flushes....so spring and autumn....They are after UREA....which just so happens citrus particularly love.....so the key is to feed them towards the end of winter with high urea to give them a good push before spring....to get the big growth surge.......Then you need to spray when u see minute buds starting to form.........They particularly feast on young and tender growth....so dont let new growth grow bigger than 5mm before you spray !...best to start from pin heads ! and then stick to the program.
NEEM oil soaks into the leaf and kills the grub....ECO oil is a surfactant which leaves a coating on the leaf.....therefore making it hard for them to get in.......So i get a 5 litre spray bottle and mix 10ml of Neem oil and 20ml of eco oil and a capful of eco feed(fish emulsion/seaweed).....it all protects the new growth and foliar feeds at the same time...Even fish emulsion has a coating effect on the leaf.....leaves already infiltrated should be pruned off....the key is to get in early when the buds are tiny......I then re spray every 10-14 days....make sure both side of leaves are sprayed and done about 6pm at night...when autumn flush comes......continue with the spray program but avoid high UREA feeds as this is what they seek......dont over feed and and promote autumn growth....the spring burst is where its at.....avoid spraying on open flowers as it will kill them and always spray at the end of the day.......The combo of neem and eco oil has been the most effective for me and i have 30 trees.....CLM can be very demoralizing when you have done everything right and you see lots of new growth.......It drove my friend so mad...he was spraying every 3 days!!!......I have not seen any sign of CLM so far this season and its 34C tomorrow and we are well into spring here............Hope this helps.......Remove all the damaged leaves    and stick to a program...i mark it on my calender every time....This is the organic solution.

Thanks millet...I thought it strange because i look after them and feed and water them correctly.....I know sandy soils have their pros and cons.

Thanks!
Time to search for a solution.

Calling Millet ....over !...he will know 4 sure mate.

The UCR collection has 3 accession types of Ugli

https://citrusvariety.ucr.edu/citrus/ugli_2780.html
https://citrusvariety.ucr.edu/citrus/ugli_4171.html
https://citrusvariety.ucr.edu/citrus/CRC4127.html

Your fruit doesn't look exactly like any of these.
The Ugli wasn't officially introduced to Australia, as far as i know, so may have come in as seed.
If it's an Ugli you may have a seed variant ??
Also looks a bit like Sanbokan

  This is getting interesting......to me it looks most like the 2780..........I have not be able to find any info on when an ugli fruit would ripen in Australia......but its going more orange everyday now and its chucking out spring growth as well.....Thanks for your input mate........I wont pick it until its nice and orange........its getting warm here now with spring....today was 26 C and 2 morrow is 30C and we have been getting plenty of cold nights......so i will take my time with it......I think i will cut it in half when i pick it and take a pick....then peel.
