You have 3 options
1 - pay the $1200 AUD to have it fixed.
2 - get a second monitor and use it.
3 - accept the loss and get a 10 Core Mac Mini M4 with 16 GB RAM and 1 TB SSD ($999 US + tax) with a 27" LG 4k monitor ($250 US + tax from Amazon.com) is $1249 US + tax which is $560 less than a similarly configured new 24" iMac ($1799 US + tax) re 07/2025.
I got the same Mac Mini M4 but with a 32" LG 4K monitor w/speakers for only $60 US more. Don't know what your sources are down under for monitors but it should be better than $1200 AUD.
