I'm in Switzerland and have 25 hops, which can be broken into:

- 1-7: Hops within my ISP's in-country network (~4ms total latency)

- 8-10: Hops within my ISP's in-Europe network (~28ms total latency)

- 11: London -> New York (~93ms total latency)

- 12: New York -> Los Angeles (~160ms total latency)

- 13: Transfer in LA from my ISP to AARNet (about the same latency)

- 14: LA to somewhere in NSW (guessing Sydney, 305ms total latency)

- 15-25: Routing within AARNet and Unimelb (319ms total latency)

So most of the latency looks to be attributed to large hops across oceans rather than internal switching. Even if you could narrow it down to London -> NY -> LA -> NSW you'd have 277ms.
