Election cycles are seasonal events and there is a traveling circus that supports them across the English speaking countries. There is also trans-national movement within political influence businesses like News Corp and other lobby groups.

Historically Australia has often adapted media from elsewhere whether it be advertising or television formats and much of the country was so isolated pre-Internet that we never noticed that football, meat pies, kangaroos and Holden cars was a ripoff of hot dogs, apple pie and chevrolet.

I expect over negative/false/deceptive campaigning would be regulated as we have a comparatively robust and fair electoral system. AI is built into popular image editing tools and political staffers aren't necessarily great graphic artists so I expect we will see more low effort AI images in political advertising and everywhere else as society continues to embrace mediocrity and deskilling.
