Five Jobs, Four Suburbs, 91 km in One Day: Inside an On-Site Engineer's Schedule
Residential · Wahroonga
Business · Macquarie Park
Students · Waterloo & Eastgardens
08:00 → 23:30
91.3 km driven
Most case studies show one fault and one fix. This one shows a whole day, because the question we get asked most often is not “can you fix it” — it is “when can you actually get here”. On 11 September 2026 the answer involved five job sites, three kinds of client and four kinds of building, between leaving Hurstville station at 8am and getting back to it at 11:30pm.

The day, job by job
08:00 → 23:30 · five job sites
1
08:00 · Depart Hurstville Station
Five bookings ahead across four suburbs — as far north as Wahroonga, back south to Hurstville at the end of the night.
2
Morning · Lucinda Ave, Wahroonga — whole-home WiFi, 400㎡+ house
At over 400㎡ a single router leaves dead zones wherever you put it. We surveyed the house, planned node placement, then installed and configured four mesh nodes so coverage and roaming hold up between rooms and across floors.
4 mesh nodes · no dead zones
3
14:00 · Khartoum Rd, Macquarie Park — business IT support, ~50 desks
Four hours on site in an office of around fifty desks: workstation setup and configuration, printer fault diagnosis, Microsoft 365 subscription and account administration, and IT asset register and maintenance — hardware, software and accounts in the same visit.
4 hours · one visit
4
19:00 · Waterloo — router dropped offline (USYD student)
Nothing in the apartment could connect. Diagnosed on site and reconfigured the router from scratch; back online before we left.
5
Same evening · Waterloo — move-in day in a two-level loft (UNSW student)
We had chosen the provider and arranged the connection the day before, and brought the right router to the appointment. The loft runs over two floors with the bedrooms far apart, and one tenant games — so we proposed a layout on the spot and configured one router on each floor, then talked the client through a recent fault on their laptop.
Online on day one of the tenancy
6
21:10 · Oscar Pl, Eastgardens — a week of support calls, fixed in 20 minutes (UNSW student)
The service had been activated a week earlier and still would not connect after repeated calls to the provider. We worked out what was actually wrong on arrival and had it live within 20 minutes, then brought up the wall ports in all three bedrooms. One tested at only 100M — faulty in-wall cabling, fixed on the same visit at no extra charge. Afterwards we helped cancel the previous provider.
20 minutes online · 3 room ports usable

23:30 · Back at Hurstville Station
Fifteen and a half hours, five job sites, 91.3 km of driving.
What a single day covers
This day was ordinary, and that is the point of publishing it: the mix below is what a normal week looks like, compressed into one timetable.
Clients, work and buildings in one day
| Dimension | Covered on 11 Sep |
|---|---|
| Clients | Household (freestanding house) · business (commercial office) · three individual students from USYD and UNSW |
| Work | Whole-home WiFi survey and mesh configuration · on-site business IT support (devices, printers, Microsoft 365, IT assets) · fault diagnosis · new connections end to end, from provider choice and plan advice to router supply and on-site install |
| Buildings | 400㎡+ freestanding house · commercial office of ~50 desks · two-level loft apartment · high-rise unit with in-wall cabling |
| Suburbs | Wahroonga · Macquarie Park · Waterloo · Eastgardens — 27.5 km from the northernmost job to the southernmost |
TAKEAWAY
The real cost of an on-site call is not the screwdriver work. It is the 91 km, the fifteen and a half hours, and the fact that you only find out what is actually wrong once you are through the door.
