Laidbaackdood, ugly fruit look nothing like your fruit.  Ugly fruit are round and pretty much smooth like an orange.

The UCR collection has 3 accession types of Ugli

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.

Millet,

GN fruits are usually ready between March to May/Jun.   Unfortunately, it is the same period of blooming.

Will the fruits remaining on the tree retard the blooming so cause alternative bearing?   The fruits can be picked up earlier but they would not taste sweet (I tried.  They were bland in March and improved gradually to May/June).

GN= Although....this fruiting time coincides with what its doing here.......spring is sept to Dec 1st ...summer dec 1st onwards.......
March at your place would be end of winter to may/june is end of spring and early summer.....Its a pity i cant find when the ripening time of ugly fruit tangor is.

Laidback, just keep watching your fruit, and then you will know the maturity date  in your area.  The very best to you.

From what I was told Ugli fruit were sometimes on sale in Nth Nsw in September. I never caught them when I was there. Yours shouldn't be far off if They are Ugli.
I think it now comes down to the tast test.

[laidbackdood]

Thanks Peeps.......yes.....the taste test and the the cut in half pic...because the ugly has a hollow chamber in the middle....so the slice in half should expose what it is........i dont think a GN will have a hollow in the middle like an ugly does.

Was wondering....in what season so golden nuggett go ripe in USA ?......because my fruit is still ripening and going orange but it hasnt gone fully orange yet and its 25-34C degrees here at the moment and well into our spring....one of the other fruit is changing to orange now........with most citrus they need night time temps to go under 10C to help acids go to sugars....so i am leaning towards this fruit ripening towards xmas and our summer......not many citrus do that here in aussie.

[Millet]

My gold nuggets are still green and rater hard. 

[laidbackdood]

Update....it is late spring here now and we are getting some days that are 30+C days.......i have two big fruits on there and both are going orange but are not fully orange.......  it has a a little spring growth but it seems to slowly be focusing on ripening those bloody big fruits on it....one fruit fell off today....about the size of a tennis ball......it was still pure green but it could be squeezed......so i peeled it and it looked like a small mandarin in size and looked orange...so i ate it ! ...it wasnt sweet at all because it hadnt fully ripened but i am now thinking its a Golden nugget......summer starts in Dec......I have fed it now with high potassium and some espom salts to encourage it to ripen.....
My question is = Do golden nuggets ripen in your summer time in the usa ?

[Millet]

My Golden Nuggets are now just starting to mature.  They are still green, but showing the very beginnings of softening.

[laidbackdood]

OK....the result is in = ITS AN UGLY FRUIT.........that big fruit that was on there...fell off the other day...so i put it in the fridge to chill.......I noticed it wasnt very heavy.....so that made me think it was juiceless......when i peeled it...the first thing i noticed it had a hollow in the middle which is a characteristic of ugly fruit...plus the segments were even and a pale yellow which is also ugly fruit style.......Unfortunately ...some of it had gone off and it wasnt really edible but at least i know what it is now.....its the ugly fruit that is grown in Jamaica....I still have one fruit on there ripening and they are supposed to be nice according to that part of the world.
