I have a brace of Eastern BTs who have been living very happily for near 10 years now on a bedding made from
course grade Kritters' Krumble
https://www.petbarn.com.au/kritters-kru ... -20-litresmixed with expanded then dried coco peat
https://www.bunnings.com.au/brunnings-9 ... k_p3023170and I mix in gum tree leaf litter ( I have an endless supply of this from my mature Bluegum that's in my front yard and continually drops leaves
( I simply collect the leaves as needed off my front lawn and path , twigs and bits of bark included )
and mix the lot with the krumble and coco peat .
If you have access to dry leaf litter, so long as the plant is non-toxic , it's a great material to use mixed with a skink's bedding.
Careful with substrates that are dusty, gritty as it can cause respiratory issues ( sneezing , blockages in the nasal passages ) and irritate the skinks eyes .
My bedding is about 3 inches deep.
I swap out my bedding once a month and remove any soiled or damp bedding as soon as I spot it. It's all composed for my garden.
My current tanks are 4ft x 2ft x 15" tall HOME MADE timber tanks made from plywood ( lined under the bedding with loose laid ceramic floor tiles ( keeps the timber dry and clean), and I use a Philips par38 80W spot to create my basking spot and temperature gradient, and 26W UVB200 globes in Nano Hoods to provide UV at the basking spot and in the warm zone.
Basking spot air temperature 35 degC , warm zone 30 degC , cool zone 26 degC.
I have two Jumbo sized HubbaHuts per tank , one doubles as the basking spot , the other is in the cool zone.

A northern will like a basking spot about 38 degC and warm zone maybe 33 degC, as they are evolved for northern woodlands and sevannahs in tropical northern WA,

NBTs only experience two seasons :
VERY HOT HUMID summers ( southern monsoon ) from October to about April
HOT dry winters .
If you want to get a handle on the climatic conditions in their natural range the Australian BoM is your best place to look :
http://www.bom.gov.au/ pick a town and you can pull out the climatic conditions and historical information for that place ( temperatures ( max , min, avg , UVI , rainfall, % RH , etc).
Water - I use tap water.
In the wild , the only permanent water sources are billabongs ( in dry rivers ) and manmade bores ( artesian water ) and farm dams (for cattles). Your skink will cope OK with "hard" tap water , the calcium in the solution in it will be beneficial.
My water dishes are extra large fake rock ones that are shallow and I replace the water every few days , more often in summer , they sit on a concrete paver , this helps keep the bedding dry and my skinks can't burrow under it and upset / spill the water .
My skinks have porcelain food dishes that I place their salad and their live insects in ( except the crickets who are hand fed to my skinks ).
I give my BTS a diet based on this :
https://www.completecritter.com/blue-tongue-skink.html , only changes I make are I never give mice and I never use dog / cat food to my skinks.
My preferred protein sources are
BSFL , silkworms, superworms, crickets and occasoionally woodies and occasionally commercially breed food snails and hard boiled eggs.
The Completecritter guide applies only to ADULT skinks, baby and juvenile skinks need more insects (protein) while growing in their first 2 years.
I give a small feed of live insects each day & salad each day. Young skinks get insects EVERY day and are offered salad, the preference is they get lots of protein and dietary calcium.
If you are buying a baby NBT or juvenile NBT , consider starting it off in a plastic tub that has see through sides , this will make it easier for it locate any live insects you give it to eat .
If the furnishings comes from a pet shop , it'll be fine.
To sterilize timber and plastic and stone (and ceramics) I us F10sc diluted 1:250.
