    Growing zone 7 or below, you should bring your Dipladenia indoors to overwinter.
    Zone 7 or above you can spread 3 inches of mulch or straw around the roots. Water only when the soil becomes dry and do not fertilize in the winter.
    Depending on the region you are in, you are either zone 6b or 7b. If the temperatures in your garden are below 45 degrees F., the plant should be brought indoors.

    These need to be fertilized once per month until winter. There are many reasons why these symptoms would happen, but this is the usual culprit.

    This is the start of a fungal infection, likely, from soil remaining too wet for too long. Make sure that the container has plenty of drainage, and if not, then make sure that it never gets rained into.

    Make sure to only water when the top two inches of soil are completely dry. This will prevent infection in the future.

    You can add a little wettable sulfur and dolomitic lime to the top of the soil, and it will help correct the issue.

    From the appearance and random pattern of the yellow spots, it appears to be a virus infecting the older leaves. If so, there is no chemical control. Since the new growth appears clear of the disease, the plant may be "out-growing" it. Keep the plant as healthy as possible with good fertility (including micronutrients) and water management.
    Viruses are often spread by insect pest vectors, like leaf hoppers and psyllids. Preventive pest management may help prevent spread of the disorder.
    I don't know your local issues and resources there on the Sunshine Coast, but check with a local nursery for organic fertilizer and pesticide products.

    Cold temperatures can kill them, but it did not likely damage them so much that they cannot be saved. Bringing them indoors can shock them a bit too.

    Technically, yes, it is a vine, but only when there is not enought light. It will seek out more by climbing. It can be kept in a bushier form with trimming, but I wouldn't press pruning too hard over winter.
