[Star Wars] What about other galaxies?

I know galaxies are farther apart, but with hyperspace tech would there not at least be attempts to go to another galaxy?

There have been attempts, and none of them have panned out very well. A Hyperspace disturbance lies outside the borders of the Galaxy, making it incredibly difficult for anyone to adventure in or out of the Galaxy. There have been a couple of attempts to go exploring outside of the Galaxy, with the most notable attempt being led by the Jedi. Suffice to say Darth Sidious and the Chiss put an end to that expedition pretty quickly. 

Bearing in mind that the Yuuzhan Vong also crossed into the Galaxy to slaughter everyone, it's not seen as an idyllic region of uncharted space to go explore. As wars are constantly raging, expedition teams won't have the financial backing or military aid of the major factions to go on these extra-Galactic journeys, and so most fail or are postponed.
