The cost of providing the necessary equipment has got to be a fraction of that to provide an ILS
Australia has less ILS equipped runways than Malaysia. Its a disgrace that we don't have more.
Some time ago I tried to get a handle on the cost of installing ILS and my recollection is that in the US they install them for somewhere between 1/5 and 1/10 of what it costs here. I also believe that the main costs here are AsA costs.
