# Ferry extension up the Brisbane River
Date: 2023-02-25

Something that comes up occasionally on comment sections that I see is
the idea of extending the CityCat upriver from UQ. I suspect it’s not
justifiable for journeys to (or past) the city but it *might* be
worthwhile for more local trips.

# Where

We’ll consider going as far as Indooroopilly in this analysis. It’s
almost the same distance from UQ as UQ is from North Quay in the CBD
(10km), and past it there’s comparatively little development on the
northern bank of the river.

There are a number of potential wharf locations:

- At Indooroopilly, the obvious place is at the old barracks site just
  downstream of all the bridges there.
- A stop is possible at Graceville along Nadine St, serving the small
  portion of that suburb outside easy walking distance to the train
  station.
- A stop at Tennyson next to the tennis centre seems to be highly
  desirable and should be part of any assumed service pattern. Tennyson
  would be just under 6km upriver of UQ.
- Depending on how far west the Tennyson stop is, an additional stop at
  Yeronga (literally at Yeronga St) might be possible. This is the
  location with the shortest possible walk to a Beenleigh-line train
  station.
- A stop on the Yeronga peninsula seems obvious and at least one is
  necessary, but the question is where to put it. A location at the end
  of Anita St seems reasonable. It’s under a kilometre to most of the
  peninsula’s housing (and the distance to the school is about the same
  as from the school to Yeronga train station).
- A stop at Long Pocket is intriguing, but current levels of development
  are fairly minimal. A proper public path along the river edge of the
  golf links up to St Lucia would probably be more worthwhile,
  especially with…
- A St Lucia stop at the Esplanade park provides a possible cross-river
  connection.
- A second, northern Yeronga-peninsula stop is another possibility. It
  wouldn’t provide access so much for Yeronga specifically, as be the
  most convenient place for a stop serving part of Fairfield.
- A Fairfield stop doesn’t seem particularly necessary. The 196 bus and
  the Eleanor Schonell Bridge are both quite close. In particular, a
  northern-Yeronga stop is almost a Fairfield stop anyway depending on
  how far west it is.

This presents us with a problem. If both the northern-bank stops are
marginal at best, then is there really any cross-river demand here other
than to UQ, or for that matter, in most places? West End to UQ and
Bulimba to Teneriffe are busy, but the Norman Park to New Farm ferry
only had a few passengers per service according to patronage data and
the Kangaroo Point to City ones aren’t much better. Every other
suburb-to-suburb cross-river pair on the CityCat is only a small
fraction of patronage; it’s mostly to the CBD stops and to South Bank.

And if there’s minimal cross-river demand then why not just improve the
buses? Extend the 196 into Yeronga and put some sort of frequentish
service through Tennyson?

# Timing

The maximum CityCat speed I’ve seen quoted is 25 knots, which equates to
just over 45 km/h. As the river is narrower and shallower and its banks
are more fragile upriver, it seems likely that we can take this as a
better-than-best case speed. Additionally, stop time must be accounted
for. Comparing a timetable from 2005 (without Milton) and one from 2021,
it takes three minutes longer to the time taken to go from Regatta to
North Quay. But looking at the timetable further downriver it’s clearly
less than three minutes per stop as some stops are only three minutes
apart! Perhaps the Go-Between and Kurilpa bridges have also slowed
things down.

With this as a basis, I estimate a absolute-best-case base time of 15
minutes from Indooroopilly to UQ, with no stops in between. To this, I
add three minutes for each of our two guaranteed stops, at Tennyson and
Anita St Yeronga.

# Timing comparisons

Riverine transport isn’t necessarily uncompetitive but for
longer-distance CBD commutes it is.

- UQ to North Quay is 22 minutes by CityCat. 30 minutes to QUT, 40 to
  Riverside.
- UQ Lakes to King George Square is about 18 minutes by 66 bus
- Indooroopilly to Central by train is about 14 minutes
- Indooroopilly (Lambert/Central) to UQ (Chancellors Place) is about 18
  minutes by the 428 bus
- Indooroopilly to UQ Lakes is an estimated 21 minutes MINIMUM by
  CityCat
  - therefore, the primary value of CityCat extension is non-city trips
- It’s about 20-25 minutes from Fairfield shops to the city by the 196
  bus (off peak), and 17 from Fairfield station to Central by train
- The 105 takes 8 minutes to get from Orsova Rd @ Brisbane Corso (NE
  point on the peninsula) to its stop outside Fairfield shops.
  Presumably a 196 extension would take a similar amount of time - no
  more than 10 minutes at least from the end of the peninsula to the
  shops and then its existing route to the city. Then again, nobody down
  the end of the peninsula wants a bus layover outside their house.
  Imagine how bad a ferry terminal would be! On the third hand, maybe
  people would be more willing to accept a ferry.
