Indeed it was mostly all previously preserved well before the 2018 election. You can view much of the corridor in the Onka Council Aldinga Fraemwork Plan. The issue was that under the previous govt, Renewal SA was looking at acquiring the southern end of the corridor for a large development, the grey section in the pic. That has now been canned.
In October 2021, Renewal SA began a process to secure a private development partner for a 60-hectare site at Aldinga. The reserved rail corridor runs directly through the earmarked land parcel. Renewal SA has now terminated its Request for Proposal process for the Aldinga site.
If you read the linked document, you'll find that RenewalSA already owns the whole of the land other than the sports grounds on the north-east corner and the Cardijn College Galilee campus on the north-west corner - both facilities which form part of the 2020 plan for the site.
No part of the RenewalSA land has ever been formally allocated to a rail corridor by either the Rann/Weatherill government or the Marshall government.
Govt ownership is clear. When I wrote acquiring, I was referring to the southern end of corridor being acquired for development rather than preserved. The issue is that last year the previous govt sought for Renewal to sell off the whole parcel to private developers for a major development in order to
increase the proposed residential density of the land - against Onka Council's wishes. Preservation of a rail corridor was unclear, but seemed unlikely as it wasn't unequivocally stated.
“Council acknowledges that the land is needed for residential development, and the final DPA (development plan amendment) approved by the minister addressed some of our concerns,” she said. “We do remain concerned about this zone’s references to high-density development, three-storey and/or more building heights, and the allowable floor area for non-residential land uses in an outer suburban location such as Aldinga. “While we ultimately didn’t get the zone we advocated for, we did get the concept plan and commitments to higher-than-minimum sustainability standards, which we consider to be important to set the foundation for development of the land.”
Thus, this potentially threatened the future rail corridor and the preferred central location of a terminus station closer to Aldinga Beach rd. It might have resulted in the future ext terminating north of Port rd, nearly 1km-1.25km further north of the general, suggested Aldinga stn site - there is no exact, current site of course.
The fact that this last 1km section of the rail corridor south of Port rd had not been previously formally gazetted, but had been assumed and indicative in planning processes and on maps for near;y a decade, has essentially now been resolved by this policy announcement. Perhaps the new govt has 'milked' the uncertainty, but at least the policy for the corridor is now clear. Something the previous govt could have avoided by making their intentions for the proposed corridor known.

Yikes! From a 2019 est of $800m, to a current rough est of $2B given much higher material prices & construction costs! Hopefully, goes down closer to the $1B mark by the end of the decade when construction of the ext should ideally commence...
