Airservices Australia (ASA) released a statement to the
public that the Civil Aviation Safety Authority (CASA) had
received a Danger Area application for Yandina Creek Quarry
on 26 August 2014, that they had reviewed the application
and decided that no Danger Area was required.
FPF obtained, under Freedom
of Information, CASA’s deliberations on the ‘Danger Area’
CASA determined that flyrock
would not reach above ground level and that any risk to
aviation safety could be managed through a blast management
protocol, including posting a sentry on top of a hill to
look out for aircraft.
CASA later confirmed that
they did not have a Danger Area application on file. FPF
discovered an informal email trail between CASA and Aviation
experts acting for Sunshine Coast Council in the quarry
development appeal case in the Planning and Environment
Court (2013). This showed consideration of the quarry at
that time centred on operations from the old 18/36 runway
and any potential risks to smaller general aviation aircraft
or helicopters flying to the north of the airport.
Evidence presented by
blasting experts in the court case showed that flyrock from
blasting had the potential to reach heights that could hit
passenger jet aircraft on approach over the quarry.
As a suitable mitigation
measure, it was suggested by CASA that a symbol be placed on
an aviation map to inform pilots flying under Visual Flight
Rules of the location of the quarry, so they would know to
avoid flying over it.
Large passenger jet aircraft
operations from the new 13/31 runway were not
considered at that time and the Planning and Environment
the development application on two conditions:
that an aeronautical
study, involving CASA be undertaken
that a Blast Management
Protocol be agreed between the quarry and the airport.
These conditions for an
aeronautical study and Blast Management Protocol are still
The quarry is not yet
operational, however the development application has been
approved and development will go ahead at some time in the
