Network Slowness because of geographic distance

I live in Australia, so the latency to all the boxes are unbearable, it’s around 400ms, so nmap, gobuster and all these enum tools sending out large amount of request are terribly slow. My home Internet speed is find, around 50Mbps, I think the reason is HTB host in EU, so the geographic distance cause the big latency. I had a AWS Kali previously sitting in US which made things better, but now the trial is close and I have to pay. So is there any hints that can help to solve this problem?
