Yes, that would appear so and has been specifically mentioned in the supplementary Scheme booklet. Namely section 2 states (as I posted the other day):-
"As neither Macquarie Mereenie (nor Santos before that) has used a material portion of their entitlement under the Mereenie interim Gas Balancing Agreement, Macquarie Mereenie has substantial volume of gas to sell under that arrangement" "...............such sales do not contractually re-set or re-balance Central's over lift, ie these sales do not enable Central to re-commence gas sales from Mereenie unilaterally. It was always envisaged with Santos that eventually there would be a marketing arrangement agreement negotiated, hence the word "interim". The value ascribed to Central by the Independent Expert has assumed that further volume can be sold.......but given the change in joint venture arrangement this, as yet, is not assured"
Note - bolds are mine.

As stated this is an Interim agreement and there is an expectation of a new arrangement but the wording in the Supplementary scheme booklet suggest Macquarie have the power to do what they want. As I posted the other day, some might view this as an implied threat, however I am certainly not suggesting this for one minute!!
But it is interesting that this and many other details have now been spelt out in the Supplementary scheme booklet................................
