Would this cage be big enough for a conure?

I found this really nice cage and since I'm getting my Maroon Bellied conure (they're about 30 cm long) soon I wondered if it would be big enough.

It is 860mm by 560mm with a height of 1450. The bird would be out of the cage for about 4 hours every day and in it for 6 hours 5 days a week except for the holidays.

Thanks.
