This data comes from the Facebook Ad Library report, which Facebook provides as part of its transparency efforts.
It's all a bit messy because Facebook does not appear to put any effort into making this efficient or simple and actively seems to avoid making it accessible outside of their own, rather horrible, API. You can access the Library directly but then you have to manually build a search each time you use it.
This gadget shows total spend since 4 August 2020 by the sitting member for the elctorate and is updated at the beginning of each month. There's no way to tie totla spend to an electorate reliably but you can do a search over all the data and then use your human brain to decide what's going on.
