Thank you for all the positive comments
Its a curious growth whilst common it doesn't grow on every gum tree and the ones near me [ across the road] are quite small and not worth bothering with. I doubt it is actually any sort of Mistletoe, its a parasitic type growth with different leaves and colour.
The tricky part is just starting, where to hold without losing it and of course where you can place the lathe steady. It did look for the most part as reasonably solid plus is weighed a few kilos.
I like these sort of pieces although I would have used a scruffy looking burr and they are far more predictable and generally very solid in the woody area . This one took various turns as it progressed, speed got lower and lower, swapping back and forth on different hollowing tools always with CA on hand to stitch thing things up. Hollowing tools I use are mainly covered or shielded type and my own version of internal scrapers.
I normally would have turned it much thinner but the area around the steady wheels began to crumble, creaking and dropping bits off etc. I had to have the main body fairly solid in order to carve the spirals. The interesting aspect was it was so darn hard, harder than most of our burrs. Hard knotty cutting with the wheels jumping ever so slightly more with each cut,. So I left it as rough, never finished to the open/rim left as is.
