Sallary Allowance and Tax Claims/Deductions

At my new job as a videographer that i started in January of last year, I've been given a $2000 a year tax free 'equipment allowance', I've spent upwards of 3-4k on equipment, and I was curious as if I can claim that full amount, or only on everything exceeding $2000.

Similarly, I have an ABN and have made business income in the financial year, not a lot (1-2k) but this is for freelance videography work, so how would claiming work here, can I do it across both? I made much more in my business last year so used all of my equipment cost as business deductions, but I've made far more now in my full time job.

Wondering the best course of action, thank you!
