In your situation i'd probably buy a new MacBook 13" base. $1799 with Edu discount, sell the free Airpods on promo at the moment and you're around the $1500ish mark at a guess.
@lowigz I would buy new as per this suggestion.
JB HiFi have it for $1638 right now which is not too far off your budget but the key here is it's new, new battery, new warranty and should last for years to come. You'll want at-least 16gb of ram and I would recommend the M4 Air over previous models for longetivity - https://www.jbhifi.co.nz/products/apple-macbook-air-13-inch-with-m4-chip-256gb-16gb-midnight
If you buy from the Apple education store you get the free airpods.
You're buying for the future, not right now.
