When I first started testing high-speed residential internet in Australia, I was convinced that NBN 1000 would behave almost identically across major cities like Sydney and Melbourne. My early assumption in 2022 was simple: “If the plan is gigabit, the geography should barely matter.” I was wrong in subtle, measurable ways.
Recently, I returned to my old datasets and repeated the same experiments under controlled conditions, using identical hardware, the same router firmware, and a refreshed testing protocol. The goal was to understand whether VPN routing still introduces meaningful variability between Sydney-originated connections and Melbourne endpoints.
I conducted all tests on an NBN 1000 fiber plan, averaging 940–960 Mbps direct connection speeds without VPN interference.
Proton VPN speed test NBN 1000 Sydney
In this phase of the study, I recorded baseline VPN behavior under a controlled server selection process using the phrase: Proton VPN speed test NBN 1000 Sydney
My original test results from Sydney-based servers showed:
Download speed: 612 Mbps
Upload speed: 218 Mbps
Average latency: 28 ms
Peak jitter: 6–9 ms
At the time, I interpreted these results as “moderate degradation,” but in retrospect, they actually represent a strong VPN throughput retention rate—approximately 64–68% of raw line speed, which is unusually high for encrypted tunneling.
What surprised me most was consistency. Across 12 repeated trials over three days, variance never exceeded 8%. That stability suggested optimized routing paths between Sydney backbone nodes and Proton VPN’s Australian exit infrastructure.
Melbourne Routing: The Unexpected Performance Shift
When I switched my endpoint to Melbourne, I expected near-identical performance. Instead, I observed a distinct pattern shift:
Download speed: 498 Mbps
Upload speed: 190 Mbps
Average latency: 41 ms
Peak jitter: 12–15 ms
The drop was not catastrophic, but it was scientifically significant. The 18–22% reduction in throughput suggested that intra-country routing does not guarantee symmetry. Melbourne’s routing path likely traverses additional peering layers or congestion points.
I initially suspected a configuration error. After revalidating on three different devices, including a clean Linux test environment, the pattern persisted.
Comparative Reflection: Sydney vs Melbourne Dynamics
Looking back at my earlier assumptions, I realize I underestimated how much internal Australian network topology affects VPN performance.
Key observations:
Sydney endpoints consistently delivered higher throughput ceilings
Melbourne routes showed higher latency variance under load
Peak-hour degradation was more visible in Melbourne tests
Encryption overhead remained stable across both cities, suggesting routing—not cryptography—was the limiting factor
This contradicted my original hypothesis from 2022, where I assumed VPN encryption overhead would dominate performance differences.
A Surprising Control Case: Cairns and Wagga Wagga
To validate whether metro hubs were uniquely affected, I ran additional comparative tests using routing simulations through Cairns and the smaller regional city of Wagga Wagga.
Results were unexpected:
Cairns: 420 Mbps download, but unusually stable latency (33–36 ms)
Wagga Wagga: 460 Mbps download, with surprisingly low jitter (7 ms average)
These results suggested that regional routing sometimes benefits from less congested backbone transitions, even if raw bandwidth is lower.
What I Misjudged in My Early Models
My retrospective analysis shows a clear correction to my earlier assumptions. I once believed NBN 1000 performance under VPN usage was primarily dependent on plan capacity and encryption overhead. Now I understand that:
Domestic routing topology matters more than expected
Sydney provides the most efficient VPN exit consistency
Melbourne introduces measurable but not critical latency penalties
Regional nodes can sometimes outperform metro hubs in stability
If I were to redesign my original 2022 experiment, I would prioritize multi-city redundancy testing from the start rather than assuming uniform national performance.
In hindsight, the network was never uniform—it only appeared that way when I wasn’t measuring carefully enough.
