It seems counter intuitive but the azimuth of sunrise (and sunset) are well below 90 deg at the summer solstice. ga has a calculator for the position of the sun and moon so you can calculate it for any date and time
http://www.ga.gov.au/bin/geodesy/run/sunmoonposnThe results for Hobart on the solstice. I had to enter a time (5:30) so it shows a little after sunrise (Altitude 4')
HOBART Lat=-42°53'00" Long=+147°17'00" Height=0.0m
AZIMUTH AND ALTITUDE OF THE SUN
Time zone: +11.00 hours
Altitude includes astronomical refraction angle for a standard atmosphere.

Computed using National Mapping Division's sunmoonposn program, version 1.1
Azimuth is the clockwise horizontal angle (in degrees minutes and seconds)
from true north to the sun/moon.
Altitude is the vertical angle (in degrees minutes and seconds)
from an ideal horizon, to the sun/moon.
An ideal horizon exists when the surface forming the horizon is at a
right angle to the vertical line passing through the observer's position on the earth.
If the terrain surrounding the observer was flat and all at the same height above sea level,
the horizon seen by the observer standing on the earth would approximate the ideal horizon.
